[PATCH] D111227: [WebAssembly] Implementation of table.grow/size and ref.null intrinsics

[Paulo Matos via Phabricator via llvm-commits]

pmatos updated this revision to Diff 380716.
pmatos added a comment.

Implements the intrinsic generating ref.null.

The test ref-null.ll passes but the implementation raised questions on how funcref is represented.
Because (apparently) IITDescriptor didn't include the ability to represent functions, I added a 
straightforward way in the current patch but it's definitely a draft version that provides food 
for thought.

Also raises questions on how to represent funcrefs that represent different FunctionTypes, i.e. 
different parameter count/type and different return type.
